7 Application filed April 30, 1919. s rial No. 293,74 1,

To all whom it may concern; v a v Be it known that I, ANTHONY Grnrores acitizen of Russia, residing at Worcester, county of WVorcester, andState of Massachusetts, have invented certain new and usefulImprovements in Railroad-Gates, of which the following is aspecification.

This invention relates to improvements 1n device for automaticallyoperating the gates at railway and roadway crossings.

The principal object of the invention is to provide means, actuated byan approaching car or train, which will cause the gates to be loweredpreventing the passing of teams, animals, or the like along the roadwaycrossing the tracks.

A further object is to provide means whereby the gates are automaticallyraised after the train has passed the crossing.

These and other like objects are attained by the novel construction andcombination of parts hereinafter described, and shown in theaccompanying drawings, forming a material part of this disclosure, andin which Figure 1 is a partial fragmentary side elevational and partialvertical sectional view, showing a conventional type of railroad andstreet crossing construction, indicating the application of theinvention.

Fig. 2 is a transverse sectional view taken on line 22 of Fig. 1, and

Fig. 3 is a diagrammatic plan view showing the arrangements of operableparts, the cables indicated by the full lines acting to lower the gate,while the cables indicated by the broken lines serve to raise the sameafter the passage of the train.

Referring to the drawings, the numerals l0 and 10" indicate pairs ofrails as used for a double track railway, the same resting upon ties orsleepers 11, while the roadway is designated by the numeral 12, the samebeing shown substantially level with the top of the running rails, atpoints between the railway tracks.

In Fig. 1 the element 15 designates a portion of a car or locomotive towhich is attached a support spring 16, engaged at its lower end with askid 17, having upturned ends 18.

At fixed intervals adjacent to the crossings, are secured in theroadbed, casings 19 in which are pivoted levers, respectively 20' @119272, v e f rm eing in length upon" the pin 21', while the lever '22 ispivoted at its end upon the pin 23,

pivoted m dway J ournaled in the upper end of the levers 20 and 22, arerollers 24 with which the train carried skids 17 makes contact, therebydepressing the levers in an obvious manner.

Arranged at the intersecting corners of the railway and roadway, areposts 25, carrying pivots 26 on which are mounted the gate elements 28,the same being arranged in palrs as is usual, and of such length, thatwhen in a downward position, as to prevent passage across the railroadtracks.

The rear ends 29 of the gate elements have engaged with them shortflexible cables 30, connectmg with counterweights 31, movable freely invertical casings 32, attached to the rear of the posts 25, and securedto the lower ends of the counterweights 31, are other cables 33, passingbelow guide pulleys 34, the cables 33 being joined together, as at 35,and continuing as at 36.

Engaged with the gate elements 28, upon the opposite side of the pivots26, are other cables 40, running under guide pulleys 41, the cablesconnected together and passing over other pulleys 42, and under guidepulleys 43, rotatably mounted in the casings 19 and connecting with thelower end of the lever 20. 4

In operation, an approaching train or car, as indicated by the numeral15, causes its attached skid 17 to make contact with the roller 24,tipping the lever 20 and exerting a pull upon the cable 40, which, beingguided over the several pulleys, causes the gates 28 to swingdownwardly, as indicated in the full line in Fig. 1. The traincontinuing, causes the skid to make contact with the pulleys set in theends of the lever 20, there by exerting a pull upon the cables 36,which, passing freely over the several guide pulleys, exerts a pull uponthe counterweight and cable connecting therewith, to the outer end ofthe gate elements, causing the gates to be raised, as shown in thebroken line in Fig. 1, and as the same arrangement operates in a reversemanner upon the adjacent track it will be seen that a train moving in aforward direction upon either track 'will automatically lower and raisethe gates at-its passage over the crossing.

Having thus described my invention What I clalin as new and desire vtosecure by Letters Patent, is

A railroad-gate operating mechanism of the character describedcomprising casings secured in the roadbed adjacent to a crossing, alever pivoted at its end in one of said casings and a second leverpivoted at its center Within the other casing, rollers at 10 the upperends of said levers adapted to be 7 Copies of this patent may beobtained for depressed by a passing train, cables guided over pulleysand. secured With one end to the gate intermediate its ends and to oneof said levers, and cables secured to the Weighted ends of said gate andto the other of said levers, substantially as described, and for thepurpose set forth.

In testimony whereof I have affixed my signature.
